[00:00:00]sorry children the current went off for that reason I have to stop in the middle so I'll start again from there so what is that any cyclic compound means this one is unsightly that is this is your studied cyclopropane sir when I say pro hard is groping 1 2 3 3 carbons you see that 1 2 3 so 1 2 3 means the whole board will be prop and single bond it is n so this four pins in cyclopropane in this way so primarily prefixes seems will be a particular kind of compound what is that Alice I keep up on all four aliphatic nor for a aromatic it is use only for a particular kind of compound beside that is an exactly compound which is on s sign hello already this remember only for an exactly now root word the root word means I said you it is nothing but your maximum number of carbon atom in the main chain in the primary chain suppose if you are having one carbon atom 1 then what is not known as Smith if to the it if 2 carbon is there in the main chain 2 carbon in the page so it is it 3 carbon prop for Garvin mute 5 & 6 X 7 kept eight 8 nine 9 ten deck we can select okay now after that what about C 11 all right what about C 11 it is undec then C 12 it is the whole deck C 13 it is drying deck then C 14 it is tetra our deck in this way you understood now C 15 and tonic heck sorry hepatic octorex not addict what about C 20 what about she turned into static no it is I cause it is I cause she twenties I cause next is for out C 21 C 21 is an i cos c 22 though i cuz similarly c 23 try like us to try Costigan and C 30 whatever C 30 now it is dry cod seed for T let me write properly then c 31 anti count on Tricon see 32 don't write on in this will goes on c 40 tetra conch in this way it goes on in this way that is a root word we can select the maximum number of carbon atom in the main chain of the prime region so children again and again I am repeatedly saying you whenever we can say come off this good organic compounds given to you what you need to do first is for us see the engine then you will predict the branches you come to know alright this is a method first see the main chain then automatically after finding the main chain whatever the nice officer dimension that is your branches that is your primary subjects okay so now Nexus let me tell you working here the children organic chemistry nomenclature which are started it's a very important one and one fact let me say you the c40 tetrachord you can see velocity where and when I was reading this I remembered one question it was asked in IIT je exams four to five years back I'm not sure about that year four to five years back it was asked now tell me the root word of that organic compound listen carefully tell me the root word I write the root word of the organic compound which contains 40 carbonate am present in it right the I what you can say name of the root word the root word are asking not the IEP team of the compound write the name of the root word of the organic compound which contains 40 carbon atoms present in it 40 40 carbonate a mistake all right so you might be thinking it is so easy questions are coming it is asking on a root word see IIT is not above the question from other planet for it it is not about the ocean from other planet IAB or any it's not about that they check your fundamentals the trigger basics then how much strong you are in your business how its strong you are in your concept if you go to questions on the previous year's Ferrante's and I always say not to go to the questions of the realism you'll get right what you can say directions for your studies int or any T they do not ask the questions which are but I can say very very rarely we talk with children cannot do know they ask always the basics of fundamental question the conceptual questions you want to check your knowledge that how much strong in your knowledge so don't the thing don't ignore so why I say I mind saying if the things that you don't ignore the small to small things you don't ignore it because you've just started you might be thinking that no I am doing this book and read that book this that had been telling me you must study no problem at all you can say but first you make your fundamental of the concepts from that you will be studying then you'll be able to understand I mean to see that I tell everybody to agree that this is enough you can study any number of books already but first of all it is not required according to me I don't like that secondly you need to make your fundamental stronger what's your fantasy stumblings you can do any questions from any book but if your funda is not strong if your base is not strong if your concept is not there then you will be but you can say getting hampered in each language every book you can set up you cannot move forward at all all right that is what I mean to say Lena whatever I said so hence to make your fundamentals from this make your basic strong so you know that when this question was asked on this particular question so I'm teaching you might be thinking that these questions it's easy now for you it is easy but when it will be asked to you after two years that you'll be appearing your itj next to next year it will be appearing right DJ exams or any two exams at that time you might be forgetting it or you need to know or it also this one of Costa Rica and ID no chance is there even many of the people they ignore and those be ignored then they got minus one because for this particular question plus four you know that in itj or any if you get one question are correct it is thus for if you get it wrong it is minus one if you lose it it is zero so many never try this one because if are this simple thing so hence don't but he can say this ignore the things and as I'm saying you you also know this fact the things which you ignore any reasons that becomes compel say questions in your exams you know this also okay so this is above the root word and secondary and primary prophets I said it to thank you very much
